Abstract Background It has been widely accepted that video-assisted thoracoscopic surgery (VATS) lobectomy is superior to conventional open thoracotomy lobectomy in many aspects. However, the direct comparison between VATS and Muscle-sparing thoracotomy (MST) has not been widely conducted. We aimed to compare the perioperative outcomes in non-small cell lung cancer (NSCLC) patients following VATS and MST. Methods PubMed, EMBASE, the Cochrane Library and Web of Science were searched for relevant studies. The retrieval time was up to April 24, 2019. Studies investigating the comparison of video-assisted thoracoscopy and muscle-sparing thoracotomy were included in our meta-analysis. Odds ratio and mean differences with 95% confidential interval were applied to determine the effectiveness of dichotomous or continuous variables respectively. Results A total of 10 studies were included with 1514 patients. Compared with MST, the incidence of postoperative complications in VATS [OR = 0.54; 95%CI(0.4, 0.73); P < 0.001] and the hospital stay [MD = -1.5; 95%CI(− 2.28, − 0.73); P = 0.0001] decreased significantly, chest tube drainage time [MD = -0.71; 95%CI(− 1.18, − 0.24); P = 0.003] were shorter and the intraoperative blood loss [MD = − 43.87; 95%CI(− 73.66, − 14.08); P = 0.004] were less in VATS group. VATS also showed a relatively longer operative time [MD = 17.11; 95%CI(2.38, 31.85); P = 0.02]. However, no significant differences were observed in numbers of resected lymph nodes, postoperative mortality, postoperative pneumonia and postoperative bleeding. Conclusion Compared with MST, VATS was associated with lower incidence of postoperative complications, shorter length of hospital stay, less intraoperative blood loss and less chest tube drainage, which showed that VATS was a comparable method to MST. Meanwhile, these results should be further conformed by more randomized control trials.
